"An uncontrolled device that routes the flow of fluids, gases and solid materials."

The most popular exhaust option is a diverter. This controlled device allows for a bolder sound that is suited for the open water. This can be achieved with a thru-hull or the operator can switch to a thru-prop for quiet entry to marinas and boat docks.

When properly configured, the Captains Call Plus can meet most noise laws within the 50 states on any Stock 502 EFI or smaller production motor. This system incorporates a diverter that allows the captain to change from an aggressive thru-hull mode to a quieter thru-prop mode with a simple helm mounted on/off switch.

This control allows for a bolder sound that is suited for the open water, or the operator can switch to a thru-prop for quiet entry to marinas and boat docks. When exiting through the transom, the exhaust passes through silencer tips that reduce the sound levels to an acceptable level. As RPMs increase, more exhaust is forced through the Y-pipe, allowing optimum flow and noise reduction. This system tames some of the loudest motors without sacrificing any performance.

This exhaust diverter allows the captain to change from an aggressive thru-hull mode to a quieter thru-prop mode with a simple helm mounted on/off switch. This control allows for a bolder sound that is suited for the open water. The operator can also switch to a thru-prop for quiet entry into marinas and boat docks. Even with an exhaust diverter installed in your boat, you may exceed the allowable noise level. If you boat in areas with noises restrictions, contact a CORSA Performance Marine representative about the Captains Call Plus system.

When properly configured with mufflers, the Quick and Quiet II can meet most noise laws within the 50 states on any Stock 502 EFI or smaller production motor. Our system enables the exhaust to exit through the transom and the prop at the same time by combining a silencer tip with the housing of a diverter (no electronics). At lower RPMs most of the exhaust will be heard through the exhaust tips. As RPMs increase more exhaust is forced through the Y-pipe, allowing optimum flow and noise reduction.
